Need help in identifying 3 separate coins for originality

First coin is possibly from the Constantino era, 2nd coin looks to be from the Roman Empire - Cocles and 3rd coin has CAESAR very readable on the surface.

Any assistance would be greatly appreciated - thank you.

3rd, Constantinus, reverse may be VOT XX

Thank you for your prompt reply. Are you saying that the Constantinus coin could be original?

Hi, yes Constantinus is good

tatinos2 - thanks very much with the help requested. Very pleased to know that the Constantinos coin is a good one. I checked in better light the reverse and for sure I see the complete wreath on the reverse, however, the verdigris is covering any lettering. Again, thank you very much with your knowledge. Might have a few more to add later in the day.
